1×10^6
Energy needed for 1 hour of running?(adult)
3.7×10^6
Explanation / Answer
1)Energy needed for for 6 hrs of running- 6×3.7×10^6
So number of candies required will be( 6×3.7×10^6)÷1×10^6
That is 22.2. so the person needs to eat minimum 23 candies
2) 1695 miles is the distance to be covered and 30 miles per gallon is the mileage
So the amount of gasoline required will be 1695÷30. i.e 56.5 gallons
If the mileage is half i.e. 15 miles per gallon than the requirement will be 1695÷15 that comes out to be 113. So yes the gasoline required is double
